AI Technical Summary

Technical Problem

Corrugated cardboard has a large amount of cellulose and hemicellulose, which is flammable. How to improve the flame retardant performance of transport cartons is an urgent problem.

Method used

By reacting isophorone diisocyanate with alcohol monomer under the action of a catalyst, a multifunctional polyurethane acrylate is generated and combined with phenylakon polyester polyol is formed to form a flame retardant coating, coated on both sides of the corrugated cardboard, light curing, and improving the flame retardant performance of corrugated cardboard.

Benefits of technology

It has achieved the improvement of the flame retardant performance of corrugated cardboard, and at the same time it has enhanced the compression resistance of the carton. It is suitable for product packaging and transportation needs, and is very practical.
